Rockets ignite propellants to produce thrust. Thrust is the physical force generated by the rocket's engines burning fuel and is required to overcome the effect of gravity. When designing rockets, engineers determine the mass of the rocket to determine how much force gravity exerts on it. Then, the thrust force generated by the rapidly burning propellant must accelerate the rocket to escape velocity (where thrust is greater than gravitational pull on the mass of the rocket)

When earth ends will it come back?
the earth isn't really going to 'end.' Jesus is going to come back and take his believers to Heaven and make a new heaven and a new earth
How does carbon come back to earth?
carbon doesn't leave earth. i think you're thinking of carbon di/monoxide.
Describe three ways people today can see the earth from above?
satillite,airplane,and rockets
How do rockets cause global warming?
When the Space Shuttle or other type of rockets goes into space, the thrust from the rockets pushes the earth from its axis causing the earth at times to shift. This could also cause to have a hole in the ozone.
Where does radiant energy transmitted to earth come from?
where does the radient energy transmitted to earth come from
What causes rockets come back to earth?
Gravity
How does single stage rockets get payload back to earth?
Single-stage rockets can't make it into space, so many of them come back down to earth when they reach a certain height. This is why most single stage rockets carry missiles, so when they fall down again, they cause massive damage to their target.
Why do rockets have potential energy?
Rockets in flight have kinetic energy. Rockets with remaining fuel have chemical energy. Rockets still able to fall back to Earth have potential energy.
What are some of the jobs rockets have done in the past?
Rockets have sent unmanned spacecraft to mars and Jupiter. Satellites put in orbit by rockets beam back information about earth's atmosphere and weather.
Will dinoaurs come back to earth?
Sadly, no. Dinosaurs are distinct so they will not come back to earth.
Do rockets drop trajectories or satellites?
A trajectory is the path a rocket takes, it is not a thing that can be dropped. Further rockets are used to "launch" a satellite into orbit, not drop it (so that it falls back to Earth).
Why do ghosts come back on earth?
Ghosts come back to earth to visit their house or to do things that they didnt finish. Ghosts probably come back to visit someone that they loved.
Are there rockets in space that will never return to earth?
Yes if a rocket fell into a black hole it will never reaturn to Earth but Sometimes NASA sends rockets unmanned ones up into space forever or when ever they want to bring it back to Earth to take take pictures of Galaxies,Planets and stars
Will curiosity come back to earth?
no
Why do rockets use thrust?
Rockets use thrust to overcome the force of Earth's gravity.
Do some rocket parts come off when the go it to space?
Yes, the booster rockets. This usually happens after their fuel has been spent, and they merely drop back to earth and land in the ocean where they are retrieved and used again for another flight.
When did Armstrong come back back to Earth?
July 21,1969
